Síndrome hemolítico urémico asociado a infección intestinal por Escherichia coli productora de shigatoxina (STEC) en pacientes chilenos: aspectos clínicos y epidemiológicos

Abstract: Introducción as infecciones por Escherichia coli productora de shigatoxina (Shigatoxin-producing Esche richia coli-STEC, en inglés) han sido identificadas como un importante problema de salud pública en países desarrollados, donde causan brotes de infecciones alimentarias y de síndrome hemolítico urémico (SHU) 1,2. Dentro de Latinoamérica, el problema parece concentrarse en países del Cono Sur-Argentina y Chile-donde existen registros de casos esporádicos de SHU durante todo el año, aunque no se han notificado… Show more

“…Although the incidence of STEC infection appears to be low, the economic losses (at the individual or national level) associated with community outbreaks and the significant costs of hospitalization required for the management of HUS and its possible sequelae, in addition to a few cases of death, justify the effort to find suitable targets against this pathogen (6). In this context, targets of vaccines have been tested in animal models with various levels of success, albeit the lack of an animal model that accurately reproduces the clinical profile of infection in humans is a considerable barrier (13).…”

“…HUS, which has a high incidence in children less than 5 years of age (6), is the most severe consequence of STEC infection and is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute renal insufficiency, which can progress to chronic renal failure (7). HUS treatment is primarily supportive, as there is no specific therapy for STEC infection.…”

“…y cols. 3 , la noción que involucra al tratamiento de las diarreas en niños con antimicrobianos como responsable de un alto riesgo de SHU, se ha convertido en un lugar común [5][6][7][8][9][10][11] , lo que dificulta la toma de decisiones pediá-tricas e impide formular proyectos de ensayos clínicos controlados (ECCs) que pudieran aportar información sólida sobre este y otros aspectos relacionados con las enterocolitis, SHU y el uso de antimicrobianos en niños. Una revisión previa (no publicada) 12 no encontró evidencias que sustentaran la proscripción de antimicrobianos en diarreas (con o sin sangre) causada por E. coli O157:H7.…”

“…3 , tanto para resolver el dilema en la práctica clínica pediátrica, que implica enfrentar las enterocolitis y las otras etiologías de SHU 5 , así como conocer el estado del problema ético que planteó desde entonces ("equipoise" desbalanceado) 13 al establecer un cuestionamiento a la investigación sobre el tema, en particular el uso de diseños intervencionistas. Nuestros objetivos no buscan preconizar el uso sistemático de antimicrobianos en diarreas de niños.…”

“…Desde então, vários surtos e casos esporádicos de colite hemorrágica e síndrome hemolítica urêmica causados por STEC têm sido reportados mundialmente (ERICKSON;DOYLE, 2007), principalmente em países industrializados do hemisfério norte, mas também há relatos em países do hemisfério sul, como na África do Sul (EFFLER et al, 2001), Brasil (GUTH et al, 2002), Austrália (NATARO; KAPER, 1998), Chile (PRADO; CAVAGNARO, 2008) e Argentina (RIVAS et al, 2006).…”
